Arsenal have 15 possible opponents in the first knockout round, including the likes of Borussia Dortmund, Napoli and Lyon.
The draw for the Europa League round of 32 will take place on Monday morning (11am UK).
Arsenal will go into the draw as a seeded team after winning Group H.
The rules are similar to the Champions League draw, where teams from the same association and from the same group cannot be drawn together.

This includes the likes of Lyon, Marseille, and Real Sociedad, who finished second in their groups.
It also includes Napoli, Borussia Dortmund and Celtic, who dropped down from the Champions League group stages and who are unseeded due to their poor records in the Champions League this season.
Here’s the full list of Arsenal’s possible opponents:
FC Astana (Kazakhstan)
Partizan Belgrade (Serbia)
AEK Athens (Greece)
FC Copenhagen (Denmark)
Steaua Bucharest (Romania)

The ties are set to be played on February 15th and February 22nd, with the seeded teams playing at home in the second leg.
